The TB7101F is a single-chip step-down DC-DC converter IC.
Equipped with a built-in high-speed and low on-resistance power
MOSFET, and utilizing a synchronous rectifier circuit, this IC can
achieve high efficiency.
Features
Capable of high current drive (I
OUT
= maximum of 1 A), using
only a few external components.
Operating voltage (V
IN
) range: 2.7 to 5.5 V.
Fixed output voltage : V
OUT
= 1.2V / 1.5V / 1.8V / 2.5V / 3.3V(typ.)
High oscillation frequency of 1 MHz (typ.), making it possible to use small external components.
Uses internal phase compensation, achieving high efficiency using only an inductor and two capacitors.
Built-in current mode architecture with excellent fast load response.
A small surface-mount type ceramic capacitor can be used as an output smoothing capacitor.
Housed in a small surface-mount package (PS-8) with a low thermal resistance.
Built-in undervoltage lock out (U.V.L.O), heatprotection, and overcurrent protection.
Marking (Note 1)/Pin Assignment
Due to its MOS structure, this product is sensitive to electrostatic discharge. Handle with care.
